MSN Explorer
Besides offering too many services, by default Windows XP setup installs software such as MSN Explorer, which isn't required for Windows XP to function properly. It wastes 13.5MB of disk space and performs forced automatic updates. Microsoft doesn't offer the ability to control automatic updates of MSN Explorer. The best thing is to remove MSN Explorer from Control Panel, Add or Remove Programs. Interestingly, Microsoft recommends that in a corporate environment, you should remove MSN Explorer and use Internet Explorer for browsing the Internet. Microsoft suggests that you use Internet Explorer because it offers better security and is customizable, yet the default configuration of Windows XP installs MSN Explorer anyway.
